I will review greylisting. On the greylisting.org site, there seems to be a number of GL-milter implementations for sendmail. Also, there is a GL-milter available on Fedora... I wonder what the consensus is for which is, for the best of, or more popular of GL-milter implementations. In review of Evan Harris's whitepaper (2003), he seems to imply (or point out) that whitelisting is not a good idea because if spammers ever discover what is on your whitelist (how, I do not know), they could, at least in theory bypass greylists.... Well, I need to review some more to make sure I fully understand the pros and cons and the necessary steps to make it work properly before attempting to do so. I am a bit fuzzy still, as if a whitelist needs to be filled in, what exactly should go into it.... more research I guess... I am not yet sure if what I have for now is sufficient for my tastes (i.e. I am not yet using greylisting) and Spamhaus and "Gene's MailList" seems to cut back a LOT of spams so far... Interesting, though, & thanks again, Dan -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
